Đánh giá hiệu quả mô hình phát điện bằng khí sinh học ở trang trại chăn nuôi lợn tại Thanh Hóa
Abstract
The article presents research results with two main contents as the following: modifying diesel generators to biogas generators and evaluating the efficiency of the biogas generator model after modified. The research was conducted in E-Green JSC with advantage technologies for original engine such as: Reduce the compression ratio, modify the ignition system, manufacture carburetor and add the speed stabilizer. The demonstration was installed at a pig farm of Viet Hung Agricultural Products JSC located at Thanh Tam commune, Thach Thanh district, Thanh Hoa province with a scale of 6,000 pigs and a 2,500 m3 Biogas covered lagoon. The results showed that the ISUZU 60kVA/48kW diesel generator converted to run fully with biogas has the following parameters of 60 kVA/36 kW, power factor 0.6 and fuel consumption 0.73 m3 gas/ kWh. This type of biogas generator has helped the farm to save up to 50% on electricity costs/month. The model operated stably and brought economical and environmental effectiveness for livestock farms.
